Answer 1

Porifera
the word for reference organism with holes. Is a non motile animals attached to some solid support. There are whole supports all over the body. This leads to a Canal system that helps in circulating water throughout the body to bring in food and oxygen. These animals are covered with hard outside layer or skeleton. The body design involves very minimal differentiation and division into tissues. They are commonly called sponges. And are mainly found in Marine Habitat example sycon kama spongilla

Annelida
Annelida animals are bilaterally symmetrical and triploblastic, but in addition they have a true body cavity. This allows true organs to be purchased in the body structure. There is, 10, extensive organ differentiation. This differentiation occurs in segmental fashion with the segments lined up one after the other from head to tail. These animals are found in variety of habitats- water, marine water as well as land. Earthworms and leeches are familiar example

Platyhelminthes
the body is bilaterally symmetrical. they are triploblastic. however, there is no true internal body cavity or coelom find the bodies flatten dorsiventrally. they are either free living or parasitic. Some example of free living animals like planaria or parasitic animals like liver flukes.

Aschelminthes
they are bilaterally symmetrical And diploblastic. However, the body cylindrical rather than flattened poem The Right issues, but no real logins, all the salt of body cavity aur pseudocoelom, is present. These are very familiar as parasitic worms causing diseases, such as the worms causing elephantiasis all the forms and the intestines. Some examples are ascaris and wuchereria

coelenterata
these are animal living in water. They show more body design differentiation. there is a cavity in the body. The body is made up of two layers of cell that is one makes of cells on the outside of the body, and the Order makes the inner lining of the body. Some of the species live in colonies like corals, while others have a solitary life span like Hydra. Jellyfish and seaanemones are common example

Answer 2

$\large{\bold{Heya..!}}$

$\huge{\mathfrak{\underline{Answer:}}}$

Kingdom Animalia is divided into ten phyla.

◻️Porifera
◻️Coelenterata
◻️Ctenophora
◻️ Platyhelminthes
◻️Aschelminthes
◻️Annelida
◻️Arthropods
◻️Mollosca
◻️Echinodermeta
◻️Chordata

Explanation:-

◻️$\bf{Porifera:-}$ These are exclusively aquatic in their habitats, mostly marine and are sedentary.They bears a large number of pores called Ostia.Body wall is supported by solicitous spicules, spongin fibers.
Body cavity sponogoel serves as digestive tract.

Some examples are:- Sycon, leucosolonia, spongilla etc.

◻️$\bf{Annelida:-}$ They may be marine , freshwater , terrestrial in their habitat .They have bilaterally symmetrical body. Body posses a true cavity coelom.
For the purpose of excretion Nephridia are present .
Annelids are usually hemaphrodite and reproduce sexually.

Some examples :- Earthworm, Nereis.

◻️$\bf{Platyhelminthes:- }$
•Also known as flatworms.
•They have organ level of organisation.
•They are acoelomates , I.e without any body cavity.
•Special cells called for cells are present for excretion.
•They are usually endoparasites get food from host by simple diffusion.

Some examples:-Planaria,Taenia sodium, fasciola hapetica.

◻️$\bf{Ascelminthes:-}$

•They are found in all types of habitat I.e.in freshwater , sea water, soil and many are endoparasites.

•Alimentary canal is complete.

•They are bilaterally symmetrical.

•Excretion is brought about by gland canal cells.

some examples :- Ascaris , wucheria.

◻️$\bf{Coelenterata:-}$

•They are sac like animals and have radially symmetrical body.

•Mostly marine but few are freshwater .

•They contain a cavity called coelenteron or gasovascular cavity.

•They exhibit polymorphism.
